You can put this solution on YOUR website!
The left side is a perfect square already, as is too the right side. You would take \"%288%2F2%29%5E2=4%5E2=16\" which is already present on the left side member.\r

\n" ); document.write( "\n" ); document.write( "\"%28x%2B4%29%5E2=36\"
\n" ); document.write( "\"x%2B4=0%2B-+sqrt%2836%29\"
\n" ); document.write( "\"x%2B4=0%2B-+6\"
\n" ); document.write( "\"x=-4%2B-+6\"
\n" ); document.write( "-
\n" ); document.write( "x is 2 or -10.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can manage the given quadratic equation as
\n" ); document.write( "\"x%5E2%2B8x%2B16-36=0\"
\n" ); document.write( "\"x%5E2%2B8x-20=0\"
\n" ); document.write( "and you can identify your c from \"ax%5E2%2Bbx%2Bc=0\" as \"c=-20\".
